Collections

The Department of Biology is home to three collections of living and preserved specimen: the Garden and Greenhouse, the Wisconsin State Herbarium, and the UW Zoological Museum. These collections are indispensable assets for teaching, research and the protection of the planet’s biodiversity.

Botany Garden and Greenhouse

The Botany Garden and Greenhouses are living laboratories for teaching, research and outreach. Our living plant collections feature 2300 plant taxa from 220 families that provide students and visitors the opportunity to explore the vast diversity of plant life from habitats around the world.
